Active clinical trials for "Pneumonia"

Current guidelines recommend early initiation of empiric antibiotic therapy to cover typical and atypical bacteria that may cause community-acquired pneumonia (CAP). Influenza antiviral therapy in patients with suspected or confirmed influenza. However, many clinicians do not suspect influenza among patients with CAP or other acute lower respiratory tract illness (LRTI) and often do not test for influenza. Additionally, results from currently available diagnostic tests for influenza may be delayed and several tests have low sensitivity and will give false negative results. Thus, anti-influenza treatment for patients with hospitalized influenza CAP and LRTI is frequently initiated late if at all. There is an association between delayed time to administration of empiric antibiotic therapy with increased clinical failure and mortality. As a result, empiric antibiotic therapy for patients with suspect CAP is begun within 4 - 6 hours of hospitalization. This has recently been demonstrated for delayed antiviral treatment as well. We hypothesize that, as happens with early empiric antibiotics for bacterial CAP, a standardized approach of adding early empiric anti-influenza therapy during the influenza season to hospitalized patients with suspect CAP and LRTI will improve clinical outcomes of patients with influenza associated CAP and LRTI. To test our hypothesis we plan a prospective, randomized, multicenter clinical trial of hospitalized patients with acute LRTI, including suspect CAP, during . If early anti-influenza medications were not included on the patients admission orders, patients will be randomized to standard care, including empiric antibacterial therapy as recommended by ATS/IDSA guidelines plus standard influenza diagnostics and treatment (Standard of care) versus early initiation of empiric antiinfluenza therapy plus standard care, e.g. empiric antibacterial (oseltamivir group). The primary study outcome will be development of clinical failure and selected clinical outcomes during the 30 days after enrollment. Other clinical outcomes that will be compared between study groups include time to clinical stability, duration of hospitalization, development of cardiovascular events, re-hospitalization, short-term mortality (30 days), and long-term mortality (1 year). The secondary study outcome will be the cost-effectiveness of the intervention.

Imipenem is a carbapenem antibacterial agent with a broad spectrum of activity against Gram-negative and Gram-positive bacteria. This agent is often used as the last line of therapy for highly resistant Gram negative bacilli nosocomial infections. In common with other beta-lactamase inhibitor, the main pharmacokinetic/pharmacodynamic (PK/PD) index that correlates with the therapeutic efficacy is the time that concentrations in the tissue and serum are above the MIC and administration by continuous infusion is the preferred mode of administration to maximize this parameter. However, in tropical countries, the stability of carbapenem antibiotics is an important consideration when considering continuous infusion. Therefore, prolonged infusion may be a useful mode of administration to maximize bactericidal activity. This study will demonstrate the stability of imipenem in clinical use at room temperature in tropical countries.

The purpose of this study is to determine the safety and efficacy of oral amoxicillin in treating WHO defined severe pneumonia(cough and fast breathing with lower chest indrawing) at home and at hospital using an open labelled multicentric prospective two-arm randomized clinical trial to determine the differences in failure of treatment with a 7 day course of oral amoxicillin administered for first 48 hours in the hospital in comparison to being sent home after enrolment, in children 3 to 59 months old who have severe pneumonia. The investigators developmental hypothesis were to test whether the community/home based oral amoxicillin is efficacious for treating severe pneumonia.

This study is planned to compare, in patients sedated, intubated and mechanically ventilated, the efficacy and safety of the Lateral Trendelenburg position in comparison to the Semirecumbent Position to prevent incidence of ventilator-associated pneumonia (VAP).

The study was performed to confirm that a single, 2.0 g oral dose of azithromycin sustained release (SR) at least as effective as 7 days of clarithromycin extended release (ER), 1.0 g by mouth once daily, when used to treat adults with mild to moderate community acquired pneumonia (CAP), and that both treatments were safe.

Many children with "non-severe pneumonia" (cough and fast breathing) have neither clinical pneumonia as assessed by physicians nor pneumonia on chest radiographs. Inappropriate use of antibiotics for these cases is leading to resistant strains of bacteria in the community. Evidence shows that almost 50% of antibiotic prescription is unnecessary.As over half of antibiotic prescription for ARI are not necessary since most of these infections are viral and do not respond to antibiotic therapy which will be source of resistance in the community. To address this issue the investigators conducted this randomized, double blind placebo controlled clinical trial of oral Amoxicillin versus placebo in children with non-severe pneumonia taking into account all the necessary safety precautions for their well being. The study hypothesis was that the clinical outcome of children 2 to 59 months of age with cough and fast breathing (WHO defined non-severe pneumonia) with or without wheezing is equivalent, whether they are treated with amoxicillin or placebo.

The impetus for this study came from the findings of the investigators' recently published study entitled "Day-care management of severe and very severe pneumonia, without associated co-morbidities such as severe malnutrition, in an urban health clinic in Dhaka, Bangladesh". If day-care management is found to have comparable efficacy to that of hospital management of severe and very severe pneumonia in children then they could be managed at outpatient, day-care set ups reducing hospitalization and thus freeing beds for management of other children who need hospital care. Such management could also be implemented in rural areas of Bangladesh and potentially to other developing countries. Additionally, availability of the treatment facility in community set-ups will be cost and time saving for the population. But, as patients with severe malnutrition were excluded from the pilot study for ethical reasons, the peer reviewers of the manuscript felt that the study findings cannot be applied to the treatment of severe and very severe pneumonia in general. Similarly, management of severely malnourished children with associated complications relies on hospital-based treatment. In another study, a day-care clinic approach by providing antibiotics, micronutrients, diet and supportive care to severely malnourished children showed that they could be successfully managed at existing day-care clinics using a protocolized approach. Therefore, after the successful conduction and publication of these two study results in international journals with severe and very severe pneumonia as well as severe malnutrition at the day-care clinic, it is mandatory to perform the final study where the investigators will include severe malnutrition as well as associated co-morbidities to be applied to the treatment of severe and severe pneumonia in children in general to make the treatment approach more widely applicable.

The purpose of this study is to assess the safety and efficacy of doripenem in participants with nosocomial pneumonia (inflammation of the lungs in which the lungs become heavy; pneumonia occurring at least 48 hours after hospital admission), complicated intra-abdominal (in belly) infections and complicated urinary tract infections (bladder infections).

This study is part of a research program too see if amikacin delivered as an aerosol directly to the lungs in combination with IV antibiotic therapy can help intubated patients with gram-negative pneumonia get better faster than when given intravenous antibiotics alone. The primary purpose of this study is to determine the correct dose of amikacin which is delivered directly to the lungs as an aerosol via an investigational device called the Pulmonary Delivery Device System (PDDS).

Head trauma and severe cerebral hemorrhage are major risk factors for development of ventilator-associated pneumonia. In a previous open labelled, single center study the investigators showed that repeated oropharyngeal decontamination with povidone-iodine may be an effective strategy to decrease the prevalence of ventilator-associated pneumonia in patients with head trauma. The present study aims to confirm these results in a multicenter, double blind study including patients suffering from head trauma or cerebral hemorrhage.
